The NASA UAP Independent Study

NASA Headquarters | Report Released 14 September 2023

NASA convened a sixteen-member independent panel of scientists, data analysts, journalists, and a former astronaut to consider whether the agency could contribute to the scientific study of UAP. The panel worked for eleven months under public scrutiny, held the first NASA UAP public meeting on 31 May 2023, and delivered a 33-page final report on 14 September 2023. The report did not conclude UAP are extraterrestrial. It concluded that the available data is mostly poor, that NASA's open-science culture could improve the quality of future data, and that the agency should appoint a Director of UAP Research to coordinate the work. Mark McInerney was named to the role the same day.

What the Report Concluded

Four propositions structured the final document.

On the extraterrestrial hypothesis
The panel found no evidence in the data made available to it that UAP have an extraterrestrial origin. It also stated explicitly that the absence of such evidence is not evidence of absence: the quality of existing UAP data is too poor to support strong conclusions in either direction. The scientific posture is to improve the data, then assess.
On evidence and the absence of evidence
On data quality
Most UAP reports lack the multi-sensor corroboration, instrumented timing, and calibrated geometry that distinguishes scientific observation from anecdote. The Department of Defence dataset, the FAA reporting stream, and civilian-witness accounts can all be improved through standardised collection protocols. NASA's open-science culture and remote-sensing infrastructure put it in a position to lead this improvement.
On the central scientific problem
On AI and machine learning
Modern artificial intelligence and machine-learning techniques can be applied to existing UAP datasets to identify patterns that human review misses. Trained models can also help separate signal from noise in noisy sensor records and flag candidate events for prioritised follow-up. The panel recommended NASA invest in AI-driven UAP analysis as a core capability.
On methodology
On stigma
The cultural stigma attached to UAP reporting actively prevents scientific engagement. Pilots, scientists, and aerospace professionals who could contribute observations or analysis are discouraged from doing so by ridicule and career consequences. Several panel members reported receiving threats during the study. Reducing stigma is itself a scientific imperative, not a peripheral one.
On the social context of UAP research

The Recommendations

The panel offered nine recommendations. Five reshaped NASA's UAP posture.

The headline recommendation was institutional. NASA should appoint a Director of UAP Research with a permanent role and a published mandate. The agency announced Mark McInerney as the appointee in the same press conference that released the report. McInerney's prior role was NASA's liaison to the Department of Defence on UAP, which gave him institutional standing across the agencies that hold the existing data. The Director of UAP Research role established for the first time a NASA staff position whose explicit responsibility includes the question.

The technical recommendations centred on data infrastructure. NASA should establish standardised metadata for UAP observations, support development of crowd-sourced reporting systems for citizen-collected sensor data (including from mobile phones), and use the agency's existing earth-observation satellites to provide environmental context for reported events. The panel proposed that NASA's open-data culture, in which scientific results and underlying datasets are published rather than classified, is the right cultural framework for the UAP question.

The aviation-safety recommendations addressed the pilot-reporting problem directly. The FAA's existing Aviation Safety Reporting System should be extended to support UAP reporting explicitly. Pilots reporting UAP should receive the same anonymity and non-punitive treatment as pilots reporting any other safety-relevant event. The Randolph and Toner contributions to the panel shaped this section.

Finally, the report recommended NASA take a public role in the question. The agency should support science communication that engages the public with UAP as a scientific topic, not a fringe one. Public-facing communications should be designed to reduce stigma while maintaining scientific rigour. The 31 May 2023 public meeting, where the panel's deliberations were broadcast live and members took questions on the record, was itself an instance of the public-engagement model the report endorsed.

The Final Report (33 pages, 14 September 2023)

Released under NASA document number "NASA UAP Independent Study Team Report". Available in the NHI Archive's government documents collection and at science.nasa.gov. The report's nine recommendations remain the framework for NASA's ongoing UAP work under the Director of UAP Research.


Significance and Reception

What the NASA study meant in the broader US institutional landscape.

The NASA panel arrived at a particular moment. The Office of the Director of National Intelligence had published its preliminary UAP assessment in June 2021. The Pentagon's All-domain Anomaly Resolution Office had been stood up in mid-2022. The House Intelligence Subcommittee held the first open congressional UAP hearing in over fifty years in May 2022. David Grusch testified before the House Oversight Committee in July 2023, just six weeks before the NASA report dropped. The panel's work was the scientific-institution leg of a four-cornered government engagement with the question that had not previously existed in coordinated form.

Reception of the report was mixed in predictable directions. Mainstream science media covered it as a measured, sober document that took a careful line. The UAP research community noted that the panel had not been given access to classified data and could only assess what was publicly available. Critics on both sides pointed out that the no-evidence-of-extraterrestrials framing was widely quoted in news headlines while the data-quality framing, which was the panel's actual conclusion, often went unreported. The pull-quote effect cut against the panel's careful position.

What the report unambiguously achieved was institutional placement. UAP research at NASA went from a topic that was not officially the agency's responsibility to a topic with a named director, a budget line, and a public-facing communications mandate. Future NASA UAP work, including any second-generation panel or instrumentation programme, would be carried out under the Director of UAP Research role established the day the report was released.


From the Archive

The panel's work bridges the May 2022 House Intelligence Subcommittee hearing (2022 US Hearing) and the July 2023 House Oversight hearing with Grusch, Graves, and Fravor (2023 US Hearing). The November 2024 follow-up House Oversight hearing (2024 US Hearing) brought Mike Gold from this NASA panel back into the congressional record with the public-engagement framing he had developed here. The European Parliament UAP meeting (2024 EU Parliament) cited the NASA study as the model for what an EU-level scientific assessment could look like. The 1952 Pentagon press conference (1952 Pentagon) is the historical anchor: the NASA study is, in effect, what the US scientific community produced when it took up the question seventy-one years after the Air Force first tried to settle it.


There is no reason to conclude that existing UAP reports have an extraterrestrial source. But if we acknowledge as much, we must also acknowledge that we do not know what most of them are, and the central scientific problem is that the data is not yet good enough to find out. NASA's job is to make the data better.
